In order to manually freeze a column (in another words - make it fixed), you need to set the
config item to
true in Handsontable initialization. When the Manual Column Freeze plugin is enabled, you can freeze any non-fixed column and unfreeze any
fixed column in your Handsontable instance using the Context Menu.
Note: to properly use this plugin, you need to have the Context Menu plugin enabled.
If you're looking for an option to programmatically fix rows or columns, see the Fixing section of this documentation.
